ESPA Drain 100 Submersible Pump

Very compact submersible electric pump for drainage; removing clean water, infiltration water and emptying ponds, swimming pools and tanks, and for household applications.

Especially recommended for applications in decorative fountains, waterfalls and pond jets.

It is designed using highly abrasion-resistant materials and it has a very compact, sturdy appearance, especially in continuous-operation applications.

They have a reliable double mechanical closure system made of silicon carbide, ceramic and graphite with ceramic, to prevent malfunctions in the electric motor. They can be supplied with a level switch included in the single-phase versions to save as much time as possible during installation and to ensure optimum automatic operation.

All parts in contact with water are coated with an anti-corrosion treatment.

Their oversized motor makes them excellent for prolonged, worry-free operation. They can operate partially submerged although, for optimum operation, it is advisable to make sure they are submerged. It allows the passage of 8-mm solids, with a suction grille at the base.

They are supplied with 10 m of cable and an external condenser.

They are equipped with 1 1/4″ H axial outlet to minimise the installation space required.
